The Pylon Technologies Co., Ltd. US2000 (VERSION B) is a Lithium-Iron Phosphate Battery designed for energy storage applications. This product manual provides comprehensive details for its installation, operation, and maintenance.

Function Description

The US2000 (VERSION B) is an energy storage product developed by Pylontech, capable of providing reliable power for various types of equipment and systems. It is particularly well-suited for applications requiring high power, limited installation space, restricted load-bearing capacity, and a long cycle life.

A key feature of the US2000 (VERSION B) is its built-in Battery Management System (BMS). This BMS is responsible for managing and monitoring critical cell information, including voltage, current, and temperature. Additionally, the BMS balances cell charging and discharging to extend the battery's overall cycle life. The system can automatically manage charge and discharge states and balance the current and voltage of each cell.

The battery offers flexible configuration, allowing multiple modules to be connected in parallel to expand capacity and power, meeting requirements for larger capacities and longer power support durations. It adopts a self-cooling mode, which rapidly reduces the overall system noise.

The US2000 (VERSION B) battery module has several important technical specifications:

Nominal Voltage: 48 V
Nominal Capacity: 50 Ah
Dimensions: 440 mm (width) x 410 mm (depth) x 89 mm (height)
Weight: 24 kg
Discharge Voltage Range: 45 V to 54 V
Charge Voltage Range: 52.5 V to 54 V
Peak Discharge Power: 5 KW for 1 minute
Peak Charge Power: 5 KW for 1 minute
Communication Interfaces: RS232, RS485, CAN
Working Temperature Range:
- Charging: 0°C to 50°C

The battery uses LiFePO4 as its cathode material, known for its safety performance and long cycle life. The BMS includes protection functions against over-discharge, over-charge, over-current, and high/low temperature conditions.

Usage Features

The US2000 (VERSION B) is designed for ease of use and installation:

Non-toxic and Environmentally Friendly: The entire module is non-toxic, non-polluting, and environmentally friendly.
Low Self-Discharge: The module has a low self-discharge rate, allowing it to be stored for up to 6 months without charging on a shelf.
No Memory Effect: It exhibits no memory effect, providing excellent performance for shallow charge and discharge cycles.
19-inch Embedded Design: Its standard 19-inch embedded design makes the module comfortable for installation and maintenance.
